Fix small thinko in IPA mod/ref pass

When a memory copy operation is analyzed by analyze_ssa_name, if both the
load and store are made through the same SSA name, the store is overlooked.

gcc/
* ipa-modref.cc (modref_eaf_analysis::analyze_ssa_name): Always
process both the load and the store of a memory copy operation.

gcc/testsuite/
* gcc.dg/ipa/modref-4.c: New test.
